[0002] The wet drum magnetic separator mainly consists of a feeding box, a permanent magnet drum, etc.( Figure 1 ) It is made of non-magnetic material - stainless steel plate by rolling and welding, and is rotated by a motor driving a reducer; the magnetic pole polarities of the magnetic system are alternately arranged along the rotation direction of the cylinder and are fixed during operation. Its working principle is: the pulp is fed into the feeding box through the uniform feeding device. Under the action of the feeding water flow, the ore particles enter the feeding area at the bottom of the box in a loose state, completing the beneficiation process. In the feeding device of the magnetic separator, there are a feeding pipe directly feeding to the feeding box and a fan-shaped slope feeding. The pulp fed directly by the feeding pipe impacts the feeding box and the feeding is uneven, resulting in low efficiency of the magnetic separator. The fan-shaped slope feeding occupies a large space and is easily worn, affecting the working efficiency of the magnetic separator. Summary of the Utility Model
